Even if ancient
games are still single threaded (which modern games are not), the benefit of more cores is the allocation of Windows background processes and tasks to other unused cores. The CPU has never really been a major bottleneck in gaming, unless you're playing compute intensive (PhysX is better, or AMD CU) or using a massive SLI setup. I wasn't saying don't go for 4.5GHz, I was just trying to help you avoid any extra hassle for a few extra brownie points. Simply said, nothing's gonna' help you avoid AMD's huge CPU dependent drivers (most DX11 games), nothing's going to help you play a horribly coded port/game far better (Batman).
If you're targeting 4.5GHz, set VCCIN to 1.98V, set LLC to Medium/Level 6, set Vcore to 1.25V, keep cache and all other voltages the same. Then test. If the rig fails, you'll need more Vcore (VCCIN is unlikely, but X99 uses a combo of both beyond the low OCs). After the rig is stable (8 hours of h264), you can start lowering Vcore in small increments until you reach failure state. Then if you really wanted to, you could also lower VCCIN too. Don't lower VCCIN until your Vcore is stable. Also your 4.5GHz clock will definitely not be Prime95 stable, but we're only aiming for realistic load scenario stability anyway. You could also use ASUS Realbench too if you wanted, but in my experience it plays havoc with certain system setups (Luxmark). Oh yeah, and keep the core temps below 75C.
